Description

  The present invention relates to a resin tile used as a lightweight roof tile.

Traditionally, ceramic tiles such as clay tiles and cement tiles have been widely used as roofing materials.

  However, since such ceramic tiles are extremely heavy, there is a problem in that workability at the time of roofing is poor, a large load is applied to the building, and the durability of the building is adversely affected.

Then, in order to eliminate the problem of such ceramic tiles, resin tiles made of thermosetting resins such as unsaturated polyester resins containing non-combustible fibers such as glass fibers are known (for example, Patent Document 1 and 2).

In addition, since the non-combustible fiber is composed of a multilayer fiber layer in which non-combustible fiber pieces are disposed on the front and back surfaces of the non-combustible fiber cloth, durability during long-term use is excellent.
Furthermore, the front layer and the back layer constituting the non-combustible fiber are made of non-combustible fiber pieces that are well-matched with the upper mold and the lower mold for molding, and the reinforcing core material layer is a non-combustible fiber having a large reinforcing effect. Because it is made of cloth, in order to improve the strength and flame retardancy, even if the content of non-combustible fibers is increased, the non-combustible fiber pieces can be made incompatible with the upper and lower molds for molding. It is possible to smoothly manufacture a corrugated resin tile, which is a commonly used tile shape, without deteriorating the molding of a thermosetting resin containing a conductive fiber. Further, as described above, the resin roof tile having the roof tile shape formed into the corrugated plate shape can be smoothly manufactured by disposing the non-combustible fiber pieces that are well adapted to the upper mold and the lower mold for molding.

  Hereinafter, the resin roof according to the present invention will be described with reference to the drawings.

  FIG. 1 is a longitudinal sectional view illustrating an embodiment of the resin roof of the present invention.

  As illustrated in FIG. 1, the resin roof tile 1 of the present invention is composed of a thermosetting resin 3 containing non-combustible fibers 2, and the non-combustible number of non-combustible fibers 2 (three in FIG. 1). Incombustible fiber pieces 22 and 22 are disposed on the front and back surfaces of the fiber cloth 21, and the thermosetting resin 3 is blended with a flame retardant material 31.

In the above invention, as the incombustible fiber 2, for example, glass fiber, carbon fiber or the like is used. As the incombustible fiber cloth 21, for example, a cloth formed by weaving the incombustible fiber 2 is used. the 22, for example, about 5～90Mm, preferably preferably used chopped strand which is cut or defibrated into short fibers of 30 to 60 mm.

  Further, as the thermosetting resin 3, for example, an unsaturated polyester resin, an epoxy resin, a phenol resin or the like is used, and as the flame retardant material 31 to be blended with the thermosetting resin 3, for example, aluminum hydroxide, three Inorganic compounds such as antimony oxide, zinc borate, barium borate, inorganic fillers such as calcium carbonate, calcium silicate, talc, mica, clay, silica, alumina, silica sand, chlorinated paraffin, chlorinated polyethylene, tetrabromo Halogen compounds such as ethane, tetrabromobisphenol A, phosphate esters such as tricresyl phosphate, cresyl diphenyl phosphate, triphenyl phosphate, trioctyl phosphate, tris (chloroethyl) phosphate, bis (2,3-dibromopropyl) ) -2,3 dichloropro Ruhosufeto, tris (2,3-dibromopropyl) - is preferred to use flame retardants such as halogen-containing phosphate esters such as phosphate.

  Moreover, when manufacturing the resin roof tile 1 of the present invention, for example, a thermosetting resin 3 solution containing a flame retardant material 31 is supplied and applied on a release film, and then on the back surface.
